` diie Stimuli referrer n in tlgest. tetttrs atent :un linking ont of tige same.

State of Vermont, have invented a new und Improved Mop-Head; and we do hereby declare thnt the following is a. full, clear,'and exact description thereof, which will enableothers skilled in the art to make and use thev same, reference being had to the accompanying drawing, 'forming pnrt of this specification.

This invention relates to a new and improved mop-head of that class in which riscrew and nut are` employed for operating the movable jaw.v The lobject'ot the ihventionis to obvinte two dillicultie's, to wit: first, the slow movement of the movable jaw in securing the mop-cloth in the head and in detaching it' therefrom; and, second, the liability of fracturing the nut in connecting the movable jnw thereto, contingencies attending the construction of the ordinary mop-heads of this class.

The accompanying drawing represents a eide sectional view of our invention.

A is o portion of the handle of the mop-head consti-noted of wood and having n rotnryjtnbulur` screw, B, fitted ou its end,` said screw B having thumb-pieces, a' a, attached for the convenience of turning it. This. 'screw B is-provided with two threads b b', nnd on the screw a nut, C, is tted, which is provided at opposite points with lateral ents orprojectons'c c. '.lhese ears or projections are drilled longitudinally and have internal screw-threads, in which 'the ende (I il'of the movable jaw D are" screwed, the ears or projections havngrone a..

right and th'e other cleft-'hand scrcw-tbreadnnd the threads on vthe end s of the jaw D also having one -a right nn-d the-others. lefthand scrowlthread, so that, by' tho turning ot' the jaw D before it and the nut are adjusted to the handle, the lends ofthe jaw will be simultaneously screwed into the ears or projections. B-y this meansthe movable jnw niny be conected to the nut C without amy trouble or ditliculty whatever. The u'snal my is to rivet the endsioi' the movable jnws in vthe ears or projections on the nut, and as the latter is c? cast ironit is frequently broken by the operation. 'The fixed jaw E is attached to the handle A just beyond the outer end of the screw B. Both the fixed and movable jaws are ot' ordinary construction,- and therefore' do not require a.'

special description. By having the screw B provided with two threads b b n. qniclc movement of the'jaw D is obtained.- I i 'v Having thus described our invent-ion, we claimde new, and desire to secure by Letters Patcnt- The connecting ot' the'movable jaw D to the mit C by means ot'Y the'right and, left screw-threads on .the endsof thejaw D;,itting in lright und let't female or internal screw-threads .in cnrs or projections c c on lth nut C, substantially :is shown und described.

.The above specification ot' our invention signed by us this 24thy day of December, 1866.
